inphone referred to the entirely 'new' system of austin taylor BT431 plugs/sockets and phones with plugs that could be used for easy parallel-connection of phones around the phone, in the days before cordless luxury. I'm showing my age by referring to it, I suppose. (introduced circa 1983).

British Telecom incorporated a touring roadshow to promote its new phones available to rent or buy, its roots to the GPO and historical exhibits. I went to the one at Trentham Gardens and was so excited being let loose with all the exotic shapes of phones and switchboards that I was verging on hysteria.

BT actually have a bit of info on old phones on their website and even mention the early push button phones like the first Genies that were still only pulse dial!
